. 1 Claim. 1

This invention relates to improvements in an adjustableroller'supporting bracket for vertically movable doors.

The principal objects of this invention are:

First, to provide a roller supporting bracket attachable to the topsection of a vertically movable door which will permit the distancebetween the door and the roller to be adjusted to correspond to thedistance between the door casing and the fixed guide rail in which theroller is to operate.

Second, to provide roller supporting mechanism for a vertically movabledoor which will permit the guide rail in which the roller is to operateto be installed more easily and with less care in determining theaccuracy of its position relative to the door casing.

Third, to provide a bracket having adjustable arms for supporting ashaft or pin at variable distances from the bracket.

Other objects and advantages relating to details of my invention will beapparent from a consideration of the following description and claim.

The drawings, of which there is one sheet, illustrate a preferred formof my roller supporting bracket operatively associated with a verticallyswingable door and a supporting guide rail therefore. v

Fig. 1 is a fragmentary vertical cross sectional view through a doorshowing the mounting of the guide rail and supporting rollers therefore.

Fig. 2 is a fragmentary inside elevational view of the upper rollerbracket and roller with the guide rail for the roller partially brokenaway in cross section.

Fig. 3 is a vertical cross sectional view through the roller supportingbracket taken along the plane of the line 3-3 in Fig. 2.

Vertically slidable horizontally hinged sectional doors for garages andother large openings are well-known and it has been common practice tosupport and guide the movement of these doors by providing guide railsalong the sides of the door opening and curving upwardly and rearwardlywithin the building. Combined hinge and roller brackets have beenattached to the door to support rollers which travel in the guide railsand thus support and direct the movement of the door. It will readily beappreciated that structures of this type require that the guide rail beaccurately positioned with respect to the casing of the door opening ifthe door which is guided by the rail is to come into close abuttingcontact with the door casing in its closed position. The lower verticalreaches of the guide rails are quite be permanently riveted in place.

which is usually supported from the roof or cross beams of the buildingis not so easily located with respect to the plane of the door casingand great difiiculty has been encountered in mounting the upper railsections so as to obtain a tight closure between the top of the door andthe top of the door casing.

In the drawings I have illustrated a wall I having a door opening 2formed therein and a vertically movable horizontally hinged sectionaldoor 3 for closing the door opening. The sections 4 of the door arejointed together by leaves 5 and 6 with the rearwardly projecting armsof the hinge leaves connected by a hinge pin 1. The pins 1 also supportrollers 8 which travel in the guide rails 9 and NJ. The upper guide railis rearwardly curved as illustrated and is normally supported within thebuilding by means of suitable straps or hangers II from the ceiling ofthe building. The foregoing construction is well-known and is describedonly to indicate the structure with which my upper roller bracket isassociated.

Secured near the upper edge of the upper door section 4 is a verticallyextending channel-shaped bracket [2 having side flanges l3. The sideflanges support an upper pivot pin l 4 which may Toward the lower endsof the flanges l3 there are formed a series of vertically spaced boltreceiving apertures 15 which are designed to selectively receive amovable hinge bolt 16. Swingably mounted on the pin M as by beingwrapped therearound is an upper hinge leaf H and swingably connected tothe bolt I6 is a lower hinge leaf [8. The hinge leaves I! and I8 areconnected at their distal ends by being folded around a pintle pin l9which forms an axle or support for the upper guide roller 20. As is bestillustrated in Fig. 3, the hinge leaves i1 and iii are cut away andoverlapped in the familiar hinge fashion with the upper hinge leaf beingbifurcated at 2| to embrace a tongue 22 on the lower hinge leaf l 8.

By employing an adjustable bracket at the upper edge of the door theupper guide rail section l0 may be installed with only reasonable careand accuracy and without painstaking measurement and adjustment relativeto the wall I. The

bracket I2 is then mounted on the top of the door with the lower hingeleaf [8 and removable bolt l disconnected from the bracket. The guideroller 20 can then be fitted to the guide rail I0 by swinging the pintlel9 and upper hinge leaf N on the pivot 14 until the guide roller en'-gages the guide rail with the upper edge ofthe door in close abuttingengagement with the casing around the door opening. With the guideroller 20 in its properly adjusted position, the.

lower hinge leaf I8 can thenbe moved to the proper set of holes l forholding the guide roller in its proper position and the bolt 16 thenpassed through the selected holes and lower leaf to complete theadjusted assembly of the bracket. It should be understood that myadjustable brackets are employed at each side of the door. and in somecases may be employed intermediate of the width of very wide doors whereintermediate upper guide rails are provided.

Having thus described my invention, what I claim as new and desire tosecure by Letters Pat-- ent is:

An adjustable bracket for mounting a guide roller on a door comprising abase member of channel-shaped cross section adapted to be secured to thedoor with its flanges projecting therefrom, said flanges having holesformed therein at longitudinally spaced points therealong, a firstsupport member pivotally secured to one end of said flanges on said basemember by a pin passed through the holes at that end of said flanges, asecond support member pivotally and releasably engaged with said flangeson said base member by a second pin passed selectively' through otherholes in said flanges, and a pintle pin connecting the distal ends'ofsaid support members and supported thereby and projecting beyond the endof the door and adapted to carry a roller.
